Problems solved by technology

The emulsifiers mentioned above all have unenvironmental factors such as being difficult to biodegrade and interfering with hormone secretion. In the post-treatment process, diaobaite is added as a reducing agent, resulting in a certain amount of formaldehyde in the emulsion, which is unsafe for the environment and the human body.
[0003] Especially APEO, which degrades slowly, is toxic and carcinogenic; and the production process of APEO will also cause pollution

Abstract

The invention discloses a preparation method of an environment-friendly acrylate copolymer emulsion. The preparation method comprises the following steps of: mixing an alkene monomer, an alkene type functional monomer, an emulsifying agent, water, an oxidizing agent and a reducing agent together and adding a pH regulator to the mixture; next, dropwise adding an initiator for 3.5 hours when the mixture is heated to 83 DEG C, thus obtaining the environment-friendly acrylate copolymer emulsion. The preparation method of the environment-friendly acrylate copolymer emulsion provided by the invention is characterized in that the acrylate emulsion which is synthesized from a surfactant free of APEO (Alkyl Phenol Ethoxylates) instead of the traditional APEO-containing surfactant, a vinyl-containing water-based functional monomer instead of the conventional protective colloid and FF6M instead of sodium formaldehyde sulfoxylate; therefore, the acrylate emulsion is formaldehyde-free and has excellent performances in terms of calcium ion stability, freeze-thaw stability, water tolerance and color display performance; and moreover, the emulsion is applicable to high PVC (Polyvinyl Chloride) in interior and exterior wall emulsion paints and capable of providing the emulsion paints with various excellent properties such as brush resistance, leveling property and weather fastness.

Description

technical field [0001] The invention relates to the technical field of material preparation, and discloses a method for preparing an environment-friendly acrylate copolymer emulsion. Background technique [0002] At present, the emulsifiers used in acrylate copolymer emulsions are mainly alkylphenol polyoxyethylene ethers (APEO), sulfates and disodium ethoxylated alkylphenol monoesters of sulfosuccinic acid. The emulsifiers mentioned above all have unenvironmental factors such as being difficult to biodegrade and interfering with hormone secretion. In the post-processing process, diaobaite is added as a reducing agent, resulting in a certain amount of formaldehyde in the emulsion, which is unsafe for the environment and the human body. . [0003] APEO, in particular, degrades slowly, is toxic and carcinogenic; and the APEO production process also causes pollution. Therefore, it is necessary to adopt new processes and formulas to produce polyacrylate copolymer emulsions, wh...
